Always liked how this synthesizer has the keyboard interface laid out, as in this way you can reach over four octaves and all the twelve notes without feeling that even on a small screen it is not cramped for space, making it easy to play polyphonically all over the tonal spectrum. The soundset is limited but charming, comes with reverb and is responsive to play. Now it is including metronome and recording so it makes it easy to feed your sampler with.For free and without advertisements!
